Second-hand smoke: harmful
According to the investigators, many people do not realize that smoke can harm their pets. These animals take in damaging particles not only through the smoke they inhale, but also through the residues that stick to their fur. As dogs and cats groom themselves by licking their coat, they also swallow the residues. An earlier study at the University of Glasgow had already demonstrated nicotine in the fur of smokers’ dogs. The increased risk of bronchitis and asthma in pets due to passive smoking had also been shown in previous studies.
